The && operator - Stuck on this challenge

Here are the directions. What am I doing wrong?

Challenge Task 1 of 1

Set the return value of the "check_speed" method to the string "safe" depending on the following condition: The speed passed in as an argument is at least 40. The speed passed in as an argument is less than or equal to 50. You should use the "&&" logical operator to accomplish this task.

ruby.rb 
def check_speed(car_speed)
  if (car_speed >= 40) && (car_speed <= 50)
    return "safe"
end

Yes, what Colin said, you forgot to close the if clause with end keyword, that's a common syntax error made by many new Ruby coders.

def check_speed(car_speed)
  if (car_speed >= 40) && (car_speed <= 50)
    return "safe"
  end
end

Alternatively, you don't have to use end if you put it all in a single statement.

def check_speed(car_speed)
  return "safe" if (car_speed >= 40) && (car_speed <= 50)
end

You ended the def but you didn't end the if statement.
